Madonna’s MDNA tour has been derailed after a truck carrying its sound equipment overturned on a highway in Sweden.

The vehicle flipped onto its side on Tuesday as it headed to the city of Goteborg, where the Material Girl is due to perform on Wednesday night (04Jul12).

One person was injured in the incident and it caused chaos on the road as the truck blocked several lanes of traffic. It is not known if Madonna was travelling in convoy with her stage equipment trucks.
